Description

Technical Field

[0001] This utility model relates to a mold removal device, belonging to the field of material handling equipment technology. Background Technology

[0002] In manufacturing fields such as injection molding and stamping, molds, as core process equipment, are generally characterized by their large size, heavy weight, precise structure, and high value. Currently, many companies, especially in small and medium-sized workshops or narrow workstations, still rely on manual handling or simple tools for mold replacement, relocation, and installation. This approach has significant drawbacks: First, it is costly and inefficient, requiring multiple workers to operate in tandem, which severely restricts rapid mold changeover and production line efficiency. Second, it poses significant safety hazards; heavy-duty handling can easily lead to muscle strain or spinal injuries for workers, and the risk of mold slippage and tipping is high, easily causing serious accidents such as limb crushing and crushing injuries. Third, it carries a high risk of mold damage; bumps, scratches, or even drops during manual handling can easily damage critical parts such as cavities and parting surfaces, affecting product precision or even causing mold scrapping and resulting in significant economic losses. Fourth, it is cumbersome and restrictive to operate; movement is difficult in narrow spaces such as between equipment or next to warehouse shelves, and collisions with surrounding facilities are likely. While existing overhead cranes and forklifts can partially replace human labor, overhead cranes are limited by the range of their tracks, and forklifts are inflexible in precision areas and take up space. Neither can meet the needs of frequent, short-distance, high-precision mold handling. Utility Model Content

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] Please refer to Figures 1 to 3 The demolding device shown in one embodiment of this application includes a base 10 and a mold moving mechanism disposed on the base 10. A moving component is disposed at the bottom of the base 10. The moving component can be a power-driven moving component or a human-driven moving component. It can be set as needed, as long as it can move the base 10. No specific limitation is made here.

[0025] The mold-moving mechanism includes a pair of parallel conveyor roller groups 20 arranged on the base 10, a push-pull assembly disposed between the conveyor roller groups 20, and a lifting assembly disposed at the bottom of the conveyor roller groups 20. The push-pull assembly includes a latch 31 inserted from bottom to top into the mold locking groove and a translational structure that drives the latch 31 to move the mold for loading or unloading. The lifting assembly is used to drive the conveyor roller groups 20 to lift, so that the latch 31 moves below the locking groove or away from the mold. The latch 31 inserted from bottom to top and the locking groove cooperate to lock the mold and the push-pull assembly, achieving self-locking under gravity, simplifying the mold-locking structure, and also preventing the mold from disengaging.

[0026] In one embodiment, the lifting assembly includes a roller 25 rotatably connected to the conveying roller group 20, a drive block 24 passing through the roller 25, a drive structure for driving the drive block 24 to move in a horizontal direction, and a connecting rod 26 hinged between the end of the conveying roller group 20 and the base 10. The drive block 24 is provided with an obliquely arranged elongated groove 241, and the roller 25 passes through the elongated groove 241. A fixed plate 21 is provided on the base 10, and a receiving cavity is formed between the fixed plate 21 and the base 10. The conveying roller group 20 is arranged on the fixed plate 21, and the driving structure is arranged in the receiving cavity. A strip groove is formed on the fixed plate 21. The driving block 24 extends from the strip groove to the upper surface of the fixed plate 21 to connect with the roller 25. Under normal conditions, the conveying roller group 20 is stationary on the fixed plate 21. When lifted, the driving structure drives the driving block 24 to move horizontally, thereby causing the roller 25 to have a tendency to move in the horizontal direction. Under the constraint of the long strip groove 241 and the connecting rod 26, the conveying roller group 20 is lifted.

[0027] In one embodiment, the drive structure includes a slide rail 28, a slider 27 slidably disposed on the slide rail 28, and a drive member for moving the slider 27. A drive block 24 is arranged on the slider 27. The guide effect of the slide rail 28 on the slider 27 ensures that the drive member drives the drive block 24 to move in the horizontal direction, thereby lifting the conveyor roller group 20.

[0028] In one embodiment, the conveying roller assembly 20 includes a pair of parallel baffles 22 and rollers 23 spaced apart between the baffles 22. Through holes are provided on the sidewalls of opposite sides of the baffles 22, and rollers 25 pass through these through holes. This arrangement ensures that both ends of the rollers 25 are rotatably connected to the baffles 22, preventing the rollers 25 from falling off and causing structural failure.

[0029] In one embodiment, the roller 25 is fixed to the drive block 24 by a bearing 251. The outer ring of the bearing 251 is fixedly connected to the drive block 24 and the roller 25. When the drive block 24 moves horizontally, the static friction between the roller 25 and the elongated groove 241 is converted into rolling friction, which facilitates the lifting of the conveyor roller group 20.

[0030] In one embodiment, the translation structure includes a pair of guide rails 32, a connecting plate 33 slidably connected between the guide rails 32, a motor 34 mounted on the connecting plate 33, and a rack 35 meshing with the motor 34. The rack 35 is arranged on the base 10 and parallel to the guide rails 32, and a latch 31 is arranged on the connecting plate 33. Thus, when the latch 31 locks with the locking groove, the mold overlaps on the connecting plate 33, further increasing the friction between the mold and the push-pull assembly and preventing the mold from falling off.

[0031] In one embodiment, the mold removal device further includes a mold locking mechanism 40 disposed on both sides of the mold moving mechanism, the mold locking mechanism 40 clamping and fixing the mold to both sides. By clamping and fixing the mold to both sides, the swaying of the mold during movement can be effectively prevented.

[0032] In one embodiment, the mold-locking mechanism 40 includes a support plate 41, a locking module 43 disposed at the bottom of the support plate 41, and a power component that drives the locking module 43 to move closer to or away from the mold. The support plate 41 is provided with a through groove, and at least a portion of the locking module 43 extends out of the through groove from the upper surface of the support plate 41. A plurality of support columns 42 are distributed on the support plate 41 to support the mold and reduce the friction between the mold and the support plate 41. The power component consists of a slide rail, a slider, and a cylinder, which are existing technologies and will not be described in detail here.

[0033] This application achieves flexible movement in narrow spaces through a base moving assembly, effectively overcoming the limitations of overhead cranes and forklifts. The lifting assembly precisely adjusts the height of the conveyor roller group, allowing the locking mechanism of the push-pull assembly to smoothly insert into or disengage from the mold locking groove. The self-locking plug-in connection ensures reliable mold gripping and release, completely avoiding the risks of slippage and tipping during manual operation. The conveyor roller group provides low-resistance rolling support for the mold, facilitating the push-pull assembly to move the mold. The entire device completely replaces manual handling, eliminating musculoskeletal injuries caused by heavy-duty operations and minimizing damage to precision working surfaces caused by mold bumps and drops, effectively ensuring personnel safety and mold lifespan.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
